Transcriptomic Analysis of Peripheral Blood Mononuclear Cells During Ostertagia ostertagi Infection in Cattle Highlights a Generalized Host Immune Reaction

open access: yesBiology
One of the most concerning ruminant infections is the parasite Ostertagia ostertagi. Known commonly as the brown stomach worm, it is ingested by grazing cattle where it then progresses its life stages, occupying the host abomasum and then the intestine ...

Radioiodine Absorption and Secretion by the Calf Abomasum

open access: yesJournal of Dairy Science, 1971
Abstract The bidirectional passage of radioiodine between the blood and abomasum was investigated in 12 anesthetized calves. Ratios of abomasal venous to arterial 131 I concentrations averaged 0.84±0.13 (sd) during 24 minutes and 0.72±0.13 at 24 hours after intravenous administration indicating 16 to 28% removal of circulating iodine by the abomasum.

The protection of the unsaturated fatty acids of dried grass and sunflower seed against biohydrogenation by rumen micro-organisms : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Animal Science at Massey University [PDF]

open access: yes, 1974
Ryegrass which had been dried and treated with HCHO was incubated with the rumen contents of a pasture-grazed cow. The protein in the grass was protected from degradation by the rumen microbes.
